To all whom it may concern:

Be it known that we, J AMES D. CAREY and BERNARD GOLDENTHAL, citizens ofthe United States, residing at New Haven in the county of New Haven andState of Connecticut, have invented a new and useful-Improvement inPipe-Cleaners; and Wade hereby declare the following, when taken inconnection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this application,and represent,

Figure 1 a top or plan view of a pipe cleaner constructed in accordancewith our invention and shown in connection with two beer pipes. Fig. 2an end view of the same. Fig. 3 a plan view of the cleaning devicedetached, on an enlarged scale. Fig. 4 a side view. Fig. 5 a rear view.Fig. 6 a sectional view on the line a-b of Fig. 3. Fig. 7 a sectionalview on the line 0cl of Fig. 3 with the T and two upper nipples inelevation.

This invention relates to an improvement in pipe cleaners, and whileespecially adapted for cleaning pipes leading from beer barrels to thefaucets, it is equally applicable for cleaning pipes of soda waterfountains, boilers or any other pipes which may be coupled in pairs.

The object of this invention is to provide a device which may be readilyconnected with two faucets or other openings from two pipes the ends ofwhich may be coupled together, and so that the cleaning solution may beforced through the pipes firstin one direction and then in the oppositedirection; and the invention consists in the construction hereinafterdescribed and particularly recited in the claim.

In carrying out our invention, we employ two cylinders 2, 3, preferablyformed from glass and closed at their ends by plates 4, 5,

secured together by bolts 6. Opening through the plate 4 into therespective cylinders are nipples 7 8, which may be connpctpd by flexibletubes 9, 10, with faucets 1 2. a

In illustrating our invention we have shown the device in connectionwith beer pipes, the faucet 11 being connected with one end of arefrigerating coil 13 which extends to a barrel 14, and the other faucet12 connected to a refrigerating coil 15 leading to abarrel 16." Intheplate 4 and leading into the cylinder 3, is a"feed-opening 17 closedsby a screw cap 18.. In the plate 5 are inlet or outlet pipes '19, 20,respectively connected with a valve-casing 21 containing a valve 22fthecasing having a passage at the top to a T 23 the opposite ends 24, 25,of'which are adapted to be respectively connected with an airsupply pipe26 and a water supply pipe 27*pro-vided with the usual control valves31, 32. Below the T a n'ipple 28 for connection with a pipe leading to adrain. The valve is adapted to open a passage from the Ttoeither of thepipes 19 and 20. When the valve is turned to allow water or air to passto the pipe 19 the passage from the pipe 20 through the nipple 28 willbe open, and when the passage is open from the T to the pipe 20 thepassage from the pipe 19 to the drain 28 Will be opened.

Preparatory to cleaning the pipes air may be forced through the coils soas to drive the contents back into the barrels or receptacles and thenthe ends 29, 30, will be disconnected from their respective barrels orreservoirs and coupled together, as shown in broken lines in Fig. 1. Asuitable cleaning solution will then be placed in the cylinder 3 throughthe opening 17 and the valve 22 will be turned so as to open the passagefrom the T 23 to the cylinder 3 at which time the cylinder 2 will havean opening to the drain. Water then being admitted through the tube 27will pass through the T and enter the cylinder 3 and force the cleaningsolution therein through the tube 10 through the open faucet 12 andthrough the coil 15 into the coil 13 from which it will pass through theopen faucet 11 and tube 9 into the cylinder 2. This cylinder beingtransparent, the operator can see when the cleansing solution hasreached the cylinder 2. When the cleaning solution has made-acir'cuitand reached the cylinder 2, .the valve 22. is reversed so as toopen the inlet into the cylinder 2 and open the outlet and forth, so tospeak, by turning the valve 22 so as to apply pressure alternately inopposite directions. When the pipes are thoroughly cleansed the Watersupply maybe shut off, and air admitted so as to drive. the.

solution out of the coils. When desired air andwater may .bealternatelyadmitted so as to aeratei the cleansing solution and assist in itsaction.

The illustration of the application of our device to 'beer, pipes willbe suiiicienti to en-- able othersto use? the same in cleansing pipesofv soda Water fiountains, boiler tubes; orany other pipesv which may becoupled together in, pairs or series so that a circuit is formedthrough- Which the cleansing solution be passed in one direction ortheother;

A. pipe cleaner comprisingtwo glass cy-l inder-s, plates: at theopposite ends, of? said cylinders, said plates connected togetherwhereby the ends of the cylinders are tightly closed; the plates at oneend formed With outlets and adapted to be coupled vwith the pipes to becleaned, the plates at the opposite ends formed with inlets, a valve;connected with said inlets and controlling the opening into eithercylinder, a T, openiing into said valve, air and Water pipesrespectively connected with opposite ends of rvsaid T, and meanscontrolled by said valve for allowingthe escape of the contents fromeither cylinder-..
